XForms, Checkbox

Motivation

You have a boolean true/false value and want an input control to have a simple checkbox for a yes/no or true/false answer.

Method

We will use a standard input control but use the bind statement to bind the instance to a boolean datatype. We will do this in two ways, one using a bind without an ID and using the bind with an id so that we can reference the bind statement.

Note that checkboxes can also be demonstrated by using the xf:select control. But in that case a
series of space-delimited values is stored in the value associated with the control.
